Interface IntBinaryOperatorWithException<E extends Exception>

Type Parameters:

E - the type of the potential exception of the function

All Superinterfaces:

ExceptionHandlerSupport<F,F>, PrimitiveReturnExceptionHandlerSupport<IntBinaryOperator>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface IntBinaryOperatorWithException<E extends Exception>
extends PrimitiveReturnExceptionHandlerSupport<IntBinaryOperator>

Represents an operation upon two int-valued operands, may thrown exception and producing an int-valued result. This is the primitive type specialization of BinaryOperatorWithException for int.

General contract

• int applyAsInt(int left, int right) throws E - The functional method.
• uncheck - Return a IntBinaryOperator
• lift - Return a IntBinaryOperator
• ignore - Return a IntBinaryOperator

int	applyAsInt(int left, int right)	Applies this operator to the given operands.
static <E extends Exception> IntBinaryOperatorWithException<E>	failing(Supplier<E> exceptionBuilder)	Returns a function that always throw exception.
static <E extends Exception> IntBinaryOperator	ignored(IntBinaryOperatorWithException<E> function)	Converts a IntBinaryOperatorWithException to a lifted IntBinaryOperator with 0 as return value in case of exception.
static <E extends Exception> IntBinaryOperator	lifted(IntBinaryOperatorWithException<E> function)	Converts a IntBinaryOperatorWithException to a lifted IntBinaryOperator with 0 as return value in case of exception.
static <E extends Exception> IntBinaryOperator	unchecked(IntBinaryOperatorWithException<E> function)	Converts a IntBinaryOperatorWithException to a IntBinaryOperator that convert exception to RuntimeException.
static <E extends Exception> IntBinaryOperator	unchecked(IntBinaryOperatorWithException<E> function, Function<Exception,RuntimeException> exceptionMapper)	Converts a IntBinaryOperatorWithException to a IntBinaryOperator that convert exception to RuntimeException by using the provided mapping function.
default IntBinaryOperator	uncheckOrIgnore(boolean uncheck)	Used internally to implements the ignore or uncheck operation.

applyAsInt

int applyAsInt(int left,
               int right)
        throws E extends Exception

Applies this operator to the given operands.

Parameters:

left - the first operand

right - the second operand

Returns:

the operator result

Throws:

E - any exception

E extends Exception

IntBinaryOperator.applyAsInt(int, int)

uncheckOrIgnore

default IntBinaryOperator uncheckOrIgnore(boolean uncheck)

Description copied from interface: PrimitiveReturnExceptionHandlerSupport

Used internally to implements the ignore or uncheck operation.

Specified by:

uncheckOrIgnore in interface PrimitiveReturnExceptionHandlerSupport<E extends Exception>

Parameters:

uncheck - create unchecked version of the function when true, else ignored version.

Returns:

the function

failing

static <E extends Exception> IntBinaryOperatorWithException<E> failing(Supplier<E> exceptionBuilder)

Returns a function that always throw exception.

Type Parameters:

E - the type of the exception

Parameters:

exceptionBuilder - the supplier to create the exception

Returns:

a function that always throw exception

unchecked

static <E extends Exception> IntBinaryOperator unchecked(IntBinaryOperatorWithException<E> function)

Converts a IntBinaryOperatorWithException to a IntBinaryOperator that convert exception to RuntimeException.

Type Parameters:

E - the type of the potential exception

Parameters:

function - to be unchecked

Returns:

the unchecked function

Throws:

NullPointerException - if function is null

PrimitiveReturnExceptionHandlerSupport.uncheck(), unchecked(IntBinaryOperatorWithException, Function)

unchecked

static <E extends Exception> IntBinaryOperator unchecked(IntBinaryOperatorWithException<E> function,

Converts a IntBinaryOperatorWithException to a IntBinaryOperator that convert exception to RuntimeException by using the provided mapping function.

Type Parameters:

E - the type of the potential exception

Parameters:

function - the be unchecked

exceptionMapper - a function to convert the exception to the runtime exception.

Returns:

the unchecked function

Throws:

NullPointerException - if function or exceptionMapper is null

PrimitiveReturnExceptionHandlerSupport.uncheck(), unchecked(IntBinaryOperatorWithException)

lifted

static <E extends Exception> IntBinaryOperator lifted(IntBinaryOperatorWithException<E> function)

Converts a IntBinaryOperatorWithException to a lifted IntBinaryOperator with 0 as return value in case of exception.

Type Parameters:

E - the type of the potential exception

Parameters:

function - to be lifted

Returns:

the lifted function

Throws:

NullPointerException - if function is null

See Also:

PrimitiveReturnExceptionHandlerSupport.lift()

ignored

static <E extends Exception> IntBinaryOperator ignored(IntBinaryOperatorWithException<E> function)

Converts a IntBinaryOperatorWithException to a lifted IntBinaryOperator with 0 as return value in case of exception.

Type Parameters:

E - the type of the potential exception

Parameters:

function - to be lifted

Returns:

the lifted function

Throws:

NullPointerException - if function is null
